  [LV] Restructure handling of -prefer-predicate-over-epilogue option [NFC]

This should be purely non-functional.  When touching this code for another reason, I found the handling of the PredicateOrDontVectorize piece here very confusing.  Let's make it an explicit state (instead of an implicit combination of two variables), and use early return for options/hint processing.
